I finally had 2 working Lyman 4 cavity molds and handles so I decided to try my hand at casting with two molds and the two furnaces that I now have. Plan was to use the 220v pot to start with and then move on to the other Lee 110V pot when it runs out. Long story short. I really think I am going to like casting with two molds at the same time. It takes a little getting used to. In my opinion you have to have a hot plate. Otherwise you simply won't get the molds up to temp and will be casting like a madman trying to get them up to temp. My process was to set both molds on the hotplate till they register about 280F. I cover them to get the temp a little more even. Then you start casting as fast as possible. They even out in temp pretty quickly and both start making good bullets at about the same time. While the sprue was cooling the stayed on the hotplate. Lyman 4 cavity molds seem to like it hot in my experiance. Once they both make good bullets I turned the plate off but they still rested on the plate while the one cooled and the other one was being filled. You are moving your arm a little more often but for me it was actually better because I never held the mold for very long. You always end up setting it down. So it was less tiring it seemed. Main thing is I wasn't going out of my mind BORED waiting for the sprue to cool. I hate just staring at the thing thinking "is it ready?". Whenevery I was going to stop I turned the hotplate back on to help keep them at temp. When one pot was empty the other was ready and I never had to wait for the lead to get to temp. I can't imagine going back to a single Lee pot. I hear the Lyman and RCBS are a little faster but I am happy with my setup for now. So, I am making bullets faster, they cool longer in the mold (which seems better to me) and I am not bored any longer. It's a win all the way around for me.
